Northrop Grumman Corporation (NOC)
has been selected to supply simplified voyage data recorders (S-VDR) for 59 Teekay Shipping vessels
Northrop Grumman’s Sperry Marine
business unit is supplying the S-VDR hardware, as well as technical support, installation kits, interface devices
, commissioning and training, through its worldwide service network
. The systems will be installed on the ships during drydock overhauls or, when possible, at pierside at a variety of ports around the world.
Similar to an aircraft’s black box cockpit recorder, the S-VDR downloads data from the ship’s navigation instruments and voice recordings from the bridge and radio communications
, which can be retrieved and analyzed following an accident at sea.
The Sperry Marine S-VDR system has been type-approved by major classification societies and national authorities to comply with International Maritime Organization
(IMO) and International Electrotechnical Commission specifications
. The IMO carriage requirements state that all existing ocean-going ships over 3,000 gross tonnage must be fitted with an approved S-VDR at the first scheduled drydocking after July 1, 2007, but no later than July 1, 2010.
